This is an illegal piece of software, often hidden from clear view when sold to the consumer. Software is often installed without agreement potentially opening exploits to the users data. DRM is a restrictive, malicious piece of code often limiting what the owner can do with their legally purchased item, be it DVD, Blu Ray or any of the many other mediums that support it. When the consumer purchases goods they should legally own that item and the works contained on it for private consumption. This should include being able to install as many times on privately owned hardware, play on any privately owned DVD/Blu Ray player and not be forced to use the predefined mediums chosen by the producers of the product. DRM removes this freedom from the user and often makes it impossible to be completely sure the product can be used on owned hardware. DRM appears, to the public at least, as a dying effort to control media from large production companies when technology has moved on and made current market platforms unrealistic. They offer no real solution for the future and currently hinder honest members of the public who legitimately purchase their goods. In any other business, harming your customer base would be seen as corporate suicide but strangely it accepted as the 'norm' in the entertainment world. A word of warning to companies that use DRM, when a product is sold containing this malicious piece of software the succeed only in turning more customers to piracy. Anyone with even a basic grasp of the internet can use Bit Torrent websites where the exact same products are readily available for free and as an added bonus have been hacked to remove DRM allowing full, unhindered use.
